Nativescript-plugin-firebase: Excessive logs on iOS

[FranciZ]

On iOS there's excessive logging after installing the firebase plugin and it's very distracting. This was described in the below issue on nativescript-cli repo.

https://github.com/NativeScript/nativescript-cli/issues/3544

Log example:

TIC TLS Event [8:0x1c4378b40]: 1, Pending(0)
TIC TLS Event [8:0x1c4378b40]: 2, Pending(0)
TIC TLS Event [8:0x1c4378b40]: 11, Pending(0)

Can you narrow it down to a certain part of Firebase perhaps? I mean, if you don't install any additional components like Google Auth, Realtime DB, etc, do you still see those messages?

[cerireyhan]

I only use Firebase-Cloud-Messaging and have been seeing those logs for a long time. Only happens in real iOS device though.

[EddyVerbruggen]

Thanks! It would be nice to know if using anything but Messaging would show the same amount logging.

[FranciZ]

Unfortunately it does. Setup a sample project with just the storage and still get the excessive logs.

firebase.nativescript.json

{
    "external_push_client_only": false,
    "using_ios": true,
    "using_android": false,
    "firestore": false,
    "realtimedb": false,
    "authentication": false,
    "remote_config": false,
    "messaging": false,
    "crashlytics": false,
    "crash_reporting": false,
    "storage": true,
    "functions": false,
    "facebook_auth": false,
    "google_auth": false,
    "admob": false,
    "invites": false,
    "dynamic_links": false,
    "ml_kit": false
}

An example of the logs:

That's good to know, thanks. So it must be because of FirebaseCore or Analytics. If you want we can rule Analytics out by disabling it (best to do it in the plist I guess): https://github.com/EddyVerbruggen/nativescript-plugin-firebase/blob/master/docs/ANALYTICS.md#analyticssetanalyticscollectionenabled

Anyway, I don't think the plugin can do anything to stop it.. so similar reports (about the native iOS Firebase SDK) should be on StackOverflow et al..

[cerireyhan]

Must be coming from FirebaseCore, I still see the logs after disabling Analytics in plist.

[EddyVerbruggen]

I don't see how the plugin can change any of that. Perhaps contact Firebase support?

[jnorkus]

Has anyone found any way to fix this? Or a reference to Firebase SDK issue? It makes it so much more difficult to debug on an iOS device!

@GrEg00z its not a proper solution as the console.dir is not working when piping
